I'm trying to get Google's OAuth2 working for user verification in an iOS app.
I'm using the OAuth2Client api but cannot get it working with google. It appears that google only accepts http://localhost or urn:ietf:wg:oauth:2.0:oob as the redirect url. Stopping me from using a custom schema to trigger a switch back to my app.
The code looks like this:
[[NXOAuth2AccountStore sharedStore] setClientID:#"<client-id>"
secret:#"<secret>"
authorizationURL:[NSURL URLWithString:#"https://accounts.google.com/o/oauth2/auth?scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.profile"]
tokenURL:[NSURL URLWithString:#""]
redirectURL:[NSURL URLWithString:#"http://localhost"]
forAccountType:#"Google"];
[[NXOAuth2AccountStore sharedStore] requestAccessToAccountWithType:#"Google"];
When I run it, Safari appears and asks for access, but then gets stuck because I cannot redirect back to the app.
Anyone know how to make this work or do I need a different api? Note: I cannot currently get access to Google toolbox OAuth2 kit ATM.
Finally got the GTM-OAuth2 code and that appears to be working.

Our iphone app allows for sign in via Foursquare via oauth. It was working fine and recently stopped working.
The error we get is: Connecting Failure: Callback uri is not valid for this consumer.
HOWEVER, if the user does not have the foursquare app installed on their phone it works fine as before. It seems as if FS is now doing a redirect to handle the oauth inside the FS app and this fails when attempting to return to the originating application. Via safari it seems to work.
This is on ios 9.
Solutions?? Thanks!
We've changed to use a SafariViewController and this seems to force Foursquare to not to this strange in-app redirect, solving the issue. This is also Apple's preferred oauth method, so probably the way to go.
Still seems like a problem on the Foursquare side that they may want to address for others however. I'm closing this question. Thanks.
Where does your redirect URL point? If you want it to launch your app after completion you should point to the iTunes store (pre-iOS9) link for your app or the universal link (iOS9 onwards).
More information on redirects for the native foursquare app is available in the README here: https://github.com/foursquare/foursquare-ios-oauth/
How to create a universal link in iOS9 https://www.appsflyer.com/blog/how-to-set-up-ios-9-universal-links-for-your-app/
A callback url is a webpage loaded after your web app has been
verified. In this case, you need to specify a page for to send data to
after authentication
Double check your Foursquare credentials and update the callback uri to a valid link. Tutorial link
Please follow the below points, may be one resolves your issue:-
Enter the callback in foursquare account in addcallback methods. Then in your code add the call back to the provider before you authorize. (Reference here).
You're getting that error because the URL you're pointing your users to (foursquare.com/oauth2/...) includes a redirect_uri parameter that doesn't match with what you configured in your app's settings under https://foursquare.com/developers/apps. Make sure these match!
I'm attempting to hook my application into Flickr but having issues during the Authentication process.
I've followed instructions in:
https://github.com/devedup/FlickrKit
I've created a CFBundleURLTypes for my application (let's call it myapp://) and tested that it works (i.e. I type myapp:// in a safari). I've successfully called the authentication URL in Flickr, it shows the login, asks the user to grant my app the necessary permissions then instead of redirecting back to my app via my URL...it does nothing, and the app is not authenticated.
I used FlickrKit demo app replacing its api key/secret/CFbundleUrltypes with mines and the issue is the same, so the problem is not in the code but rather in the way i registered my app in flickr. Said that...I just followed the instructions in Flickr "Edit Authentication Flow" so I guess the issue is with the callback url I put in flickr. I used myapp://auth? as described in many posts in the internet but does not authenticate or call back my app.
This is not the same issue reported here:
Flickr Authentication Flow and iPhone
but rather similar to the unanswered post:
flickr callback URL not working
The Info.plist for the custom URL handler and the AppDelegate code are a copy&paste from the flickrKit demo app [no need to reinvent the wheel] and anyway even after changing api key secret and url in flickrKit demo app with mines...the app is not called back, so it must be something wrong in my app registration.
Anybody experienced a similar behavior ? i ruled out objective-c code and callback url as the issue, so what is left is the flickr part but not sure where to look for help... so i wrote this post.
Thanks for any tip,

Probably this is a problem of api signature calculation. All the parameters passed via method should be used to calculate an api signature.
I'm developing an app using Phonegap and it implements a Facebook login to save some data using the user_id as a reference. I'm using OAuth.io library to implement the login dialog and everything runs smoothly in the web browser and in Android but when I test the app in XCode and I tap the login button the following error appears.
Cannot find hostname in file:/// from static
code: InvalidHeader
message: Cannot find hostname in file:/// from static
My guess is that it has something to do with phonegap not making an external request since the app is not actually hosted in a domain but running locally... any thoughts?
Seems like you are using oauth.js library instead of phonegap version
In your main page "index.html" add reference to the correct js file
<script src="oauth-phonegap.js"></script>
Then follow the instructions here to build your application
I had a simular issue using oauth.io. Turns out it was my Ajax prefilter changing the REQUEST to Facebook(it was adding parameters to the header for each request). Wether this is your issue or not, what you need to do is compare a successful REQUEST to Facebook to an unseccussful one, that will show you where things go wrong. Alternativly a blank phonegap app with no extra code other then the required oauth code should work and will be a Good starting point to isolate your issue.
I have been using Phonegap 2 years before.Though I didn't connect to facebook before,I connected to other website by OAuth.I can show you my solution.
Firstly,you should know how OAuth works.You can read OAuth 2.0 from facebook developer website or other websites.
Secondly,you should know your target:token,uid,expires_time.The most important thing is token.
Thirdly,just do it.In 2010,I solve this problem by using Phonegap Childbrowser plugin(now Phonegap have a inAppBrowser) and a light server.
Why I should use a light server?The server can help me to handle the redirecting in OAuth service and do cache.
Step 1 : I wrote script to connect with my server,and my server connect to OAuth Service(facebook).
Step 2 : OAuth Service(Facebook) do response and redirect to Facebook login page.
Step 3 : After input username and password,OAuth Service(Facebook) will redirect to another url and do a callback with some code or token.
Step 4 : If you get the token,save it and use it to connect OAuth Service(Facebook) if you want.
When I saw "Cannot find hostname in file:/// from static " in your description,I know that maybe you get confuse in OAuth.Now,I suggest you some server side code to handle it and make your OAuth process possible.
I am developing an iOS app and want to implement native sign in via Twitter. I am using an example I found here that includes 2 steps, request token and access token. For the second step I use my twitter ACAccount (account.framework) and my app consumer_key and consumer_secret, and finally obtain an oath_token and oath_token_secret.
The problem is that when I try to fetch data with that token in my app API I get invalid token.
I think a step might be missing here or something. I look at every post related to sign in via Twitter and couldn't solve this...
Thanks everyone
This is the example I based my code

I did almost everything the same, I am using ARC
I'm trying to get a iOS client to make use of Yammer's Oauth2 to validate a user. I first tried the GTM-OAuth2 code, but I cannot get it to understand the response from Yammer. It appears that the GTM code is expecting the access_code as a query parameter, where as Yammer is returning it as a uri fragment. I hack he GTM code to see the fragment, but now it appears to be thinking that there is an error because the code and message fields are not in the response from Yammer.
I've also tried to use OAuth2Client api but the problem there is that Yammer does not seem to want to use the redirect_uri I pass to it, so Safari never gets the custom url and therefore never calls back to the app.
Does anyone have a working example of using Yammer's OAuth2?
I would also be interested if anyone has got GTM-OAuth2 to work with Facebook?
Yeah Yammer has a shitty implementation of oAuth. Looks like each service has taken its own implementation of oauth. anyway yammer requires the user to copy a 4-digit code from its website, go back to your service paste that code in your website. Only then you can request for access code.
check this - http://www.tutorialjinni.com/2011/04/yammer-api-example.html (its in php but hope you can get the gist).
Nothing you can do about it but a fun read - Yammer API sucks
